  In the present embodiment, as an example, the stand 2 holds the television receiver 1 in a state in which the vent 22 provided in the housing 3 of the television receiver 1 is exposed. As shown in FIGS. 2, 4, and 5, the vent 22 is provided in the second part 3 </ b> Bb and the inclined part 3 </ b> Bc of the housing 3. As shown in FIGS. 1, 9 and 10, the vent 22 is located above the upper end (edge, side) 2 j of each part of the second support part 2 b and is not covered by the stand 2. , Exposed. Therefore, as an example, it is easy to suppress the air (air flow) passing through the vent 22 from being blocked by the stand 2. Further, the opening 3 u of the connector 21 provided in the housing 3, the opening 17 a of the component accommodating portion 17 that accommodates the component 16, the opening 3 u of the operation portion 20, and the like are also exposed. Therefore, in this embodiment, as an example, it is easy to suppress that the stand 2 prevents the access and operation of components, fingers, and the like with respect to the openings 3u and 17a. Further, with the above configuration, the second part 3 </ b> Bb of the housing 3, which is an example of a region with a large amount of heat generation in the housing 3, is exposed from the stand 2. Therefore, as an example, compared with the case where 2nd part 3Bb is covered with the stand 2, heat dissipation tends to become large. As an example, the cooling efficiency tends to be high.

  In the present embodiment, as an example, as shown in FIGS. 9, 11, and 13, protrusions (projections) 2 m and 2 n are provided on the surface (front surface) 2 k of the wall 2 f that supports the housing 3. It has been. Specifically, as shown in FIG. 11, a plurality of (in the present embodiment, two as an example) protrusions 2m are arranged at intervals along the end 2j of the wall 2f. The projecting portion 2m extends with a substantially constant width along the direction I (the forward / backward direction, the inserting direction, the attaching / detaching direction, and the attaching direction) I of the housing 3 with respect to the stand 2. Further, as shown in FIG. 9, the outer edge (end edge, front edge, tip, front end) of the protrusion 2m is bent into a shape that is convex toward the normal direction of the wall 2f. Further, as shown in FIG. 11, a plurality of (in this embodiment, two as an example) protruding portions 2n are positioned along the end portion with the wall portion 2g. The protruding portion 2n extends with a substantially constant width along the direction I of the housing 3 with respect to the stand 2. Further, as shown in FIG. 13, the outer edge (end edge, front edge, tip, front end) of the projecting portion 2n extends in a plane along the surface 2k of the wall portion 2f in parallel with the surface 2k. . The protrusions 2m and 2n are in contact with the rear surface (surface, second surface) 3b of the housing 3. The protrusions 2m and 2n are provided apart from each other at different positions along the entrance / exit direction of the casing 3 to / from the stand 2, and are provided apart from each other at different positions along the direction orthogonal to the entrance / exit direction. It has been. Therefore, according to the present embodiment, as an example, the housing 3 of the television receiver 1 positioned at a predetermined position is mutually positioned at a plurality of positions from the rear (rear side, rear surface side, rear surface side, rear side). Are more stably supported by the projecting portions 2m and 2n that are spaced apart from each other. Further, as shown in FIG. 13, the protrusions 2m and 2n separate the surface 2k of the wall 2f from the rear surface 3b of the housing 3, and provide a gap g1 between the surface 2k and the rear surface 3b. Therefore, in the present embodiment, as an example, the frictional force due to the contact between the surface 2k and the rear surface 3b increases, and the housing 3 of the television receiver (electronic device) 1 becomes difficult to move with respect to the stand 2. Is suppressed. Further, as an example, an air flow in the gap g1 is easily secured, and accordingly, the cooling performance is easily increased. In the present embodiment, as an example, as shown in FIG. 13, the protruding portion 2 p is also provided on the back side (rear side, rear surface side, back side, rear side) of the wall portion 2 h. This protrusion 2p is in contact with the front surface (surface, first surface) 3a of the housing 3. A gap g3 is also provided between the surface 3a of the housing 3 and the surface (back surface, rear surface) 2s of the wall 2h. This protrusion 2p can also contribute to more stable holding of the casing 3 of the television receiver 1 at a predetermined position.

  In this embodiment, as an example, as shown in FIGS. 11 and 15, the wall 2e is provided with an opening 2r, the connector 43 is exposed from the opening 2r, and protrudes onto the wall 2e. ing. 17 and 18, the connector 43 enters the housing 3 through the opening 3 u of the housing 3 of the television receiver 1, is coupled to the connector 19, and is electrically connected to the connector 19. Is done. In addition, a protruding portion (protrusion, guide) 43 a that serves as a guide when coupled to the connector 19 is provided at a corner portion that is a side end portion and a tip end portion of the connector 43.

In the present embodiment, as an example, the connector 43 and the board 42A are supported by the housing 40 via the elastic portion 48 as shown in FIGS. Specifically, the elastic portion 48 includes an elastic material (for example, a metal material, a synthetic resin material, an elastomer, or the like) at least partially (arm portion 48a). The elastic part 48 includes an arm part (extension part, suspension part, connection part, span part, bridging part, displacement part, elastic deformation part) 48a and a fixing part 48b. The arm portion 48a extends between the board 42A to which the connector 43 is fixed and the fixing portion 48b fixed to the housing 40. Depending on the specifications of the arm portion 48a (material, shape, direction, length, width, height, thickness, curvature of the curved portion, etc.), the elastic force (elastic repulsive force) of the elastic portion 48, hardness, displacement, The insertion force (pushing force when mounting) or the like can be variably set. As an example, the arm portion 48a is bent in an S shape. The fixing portion 48b is coupled to the housing 40 by a coupling tool such as a screw 49. In this embodiment, as an example, the connector 43 is supported at both ends by two elastic portions 48. That is, the connector 43 is sandwiched between the two elastic portions 48. With such a configuration, as an example, the connector 43 can be more stably supported as compared to a case where the connector 43 is cantilevered. In the present embodiment, as an example, the arm portion 48a is a belt-like and plate-like member having a surface along the direction of entering / exiting the stand 2 of the casing 3 of the television receiver 1, and the direction of entry / exit Are bent along a direction (in this embodiment, an orthogonal direction, an orthogonal surface, for example). Therefore, the arm portion 48a is easily displaced in the direction intersecting with the entry / exit direction and is not easily displaced in the entry / exit direction. Therefore, according to the present embodiment, as an example, when the housing 3 of the television receiver 1 is displaced in a direction crossing the entrance / exit direction with respect to a predetermined position, the connector 43 is moved corresponding to the displacement. Cheap. That is, the displacement of the connector 19 with respect to a predetermined position is easily absorbed by the elastically displaceable connector 43. Further, according to the present embodiment, as an example, the connector 43 can be held more firmly against the connector 19 of the television receiver 1 that moves along the exit / entry direction. Therefore, as an example, the television receiver (electronic device) 1 can be easily attached to and detached from the stand 2. That is, according to the present embodiment, by providing the elastic portion 48 (arm portion 48a) having different elasticity (rigidity) depending on the direction, as an example, it is easy to absorb misalignment (easy to handle) and attach / detach. It is easy to balance ease.

  In the present embodiment, as an example, as shown in FIG. 17, a connector 43 to which the connector 19 of the television receiver 1 (electronic device supported by the stand 2) is connected is provided in the housing 40. Apart from the substrate 42A, the connector 44 other than the connector 43 (for example, a power connector, a video signal connector (for example, HDMI connector, D terminal connector, DV terminal connector, etc.), an audio signal connector (for example, phone terminal) Connector, DIN connector, etc.), data signal connector (eg, USB connector, LAN connector, RS-232C connector, etc.), radio wave connector (eg, coaxial cable connector, etc.), optical fiber connector, etc.) Is provided. That is, in the present embodiment, as an example, a plurality of (in the present embodiment, two as an example) substrates 42A and 42B are provided in the housing 40. The substrate 42B is positioned away from the substrate 42A. In the present embodiment, as an example, the substrate 42B is positioned behind the substrate 42A (on the opposite side of the display screen 4a). Moreover, the board | substrate 42A and the board | substrate 42B are also spaced apart also in the height direction. In the present embodiment, as an example, the substrate 42B is provided at a position higher than the substrate 42A (away from the placement surface P). As described above, by arranging the plurality of boards 42A and 42B so as to be separated from each other, for example, the degree of freedom of component layout is easily increased, and as an example, the stand 2 can be configured more compactly. In addition, as an example, the position of the connector 44 provided on the board 42B can be set regardless of the position of the board 42A or the connector 43. An effect such as being easily suppressed from being hindered is obtained. Further, as an example, the connector 44 can be provided at a position where the proximity of the components and fingers is easier and the operation becomes easier.

  In the present embodiment, as an example, as shown in FIGS. 16 and 17, the board 42 </ b> B and the connector 44, the electronic component 45, and the like provided on the board 42 </ b> B are included in the component housing portion 41 (housing 40). The shield members (shield portion, cover member, cover portion, surrounding member, cover member, shielding member, conductor, conductive member) 50 and 51 are covered. Specifically, the shield member 50 has a plurality of wall portions 50a to 50c, and the shield member 51 has a plurality of wall portions 51a to 51c. The surface (first surface, upper surface) 42Ba and the opposite surface (second surface, lower surface) 42Bb of the substrate 42B are provided in parallel with the placement surface P (in the present embodiment, as an example, in parallel). ing. The wall 50a is provided in parallel with the surfaces 42Ba and 42Bb of the substrate 42B (in the present embodiment, as an example in parallel), and covers the substrate 42B from above. The wall portion 50b extends in a direction intersecting with the wall portion 50a (in the present embodiment, a direction orthogonal as an example), and covers the substrate 42B from the front (the television receiver 1 side). The wall portion 50c extends in a direction intersecting with the wall portions 50a and 50b (in the present embodiment, a direction orthogonal thereto as an example), and the substrate 42B is laterally (left and right as viewed from the front of the television receiver 1). From the left and right sides of the The wall 51a is provided in parallel with the surface 42Bb of the substrate 42B (in this embodiment, as an example in parallel), and covers the substrate 42B from below. For example, the shield members 50 and 51 are made of a conductive material or a magnetic material. Thus, in this embodiment, as an example, the board 42B and the connector 44 and the electronic component 45 provided on the board 42B are covered by the shield members 50 and 51 (the wall parts 50a to 50c and the wall part 51a). It was broken. Therefore, as an example, in a circuit related to the board 42B, the connector 44, the electronic component 45, and the like, it is easy to suppress noise mixing with respect to the electrical signal, and it is easy to suppress adverse effects on the electrical signal. In addition, due to the shield members 50 and 51, for example, the rigidity of the housing 40 is likely to increase. Moreover, since the shield member 50 is provided in a box shape, as an example, the rigidity of the housing 40 is likely to be further increased. In the present embodiment, as an example, as shown in FIG. 17, the shield member 51 is parallel to the wall 51 a (in the present embodiment, in parallel as an example), and the placement surface P from the wall 51 a. Wall 51b spaced apart at a position close to (downward), and extending in a direction crossing the walls 51a and 51b (in the present embodiment, a direction orthogonal to the example), the wall 51a and the wall 51b Wall portion 51c extending between the two. Therefore, according to the present embodiment, as an example, the shield member 51 makes it easier for noise to the electrical signal to be suppressed, and as an example, the rigidity of the housing 40 tends to be further increased. According to the present embodiment, as an example, the shield members 50 and 51 can also function as a part of the frame 47. In the present embodiment, as an example, as shown in FIG. 16, a frame 47 different from the shield members 50 and 51 is provided in the housing 40 along the wall 2f. The frame 47 is configured in a plate shape, has a plurality of projecting portions (frame portions) 47a, and is provided with a plurality of through holes 47b. Thereby, as an example, the frame 47 can be configured to be lighter, and the rigidity of the housing 40 tends to increase. In the present embodiment, as an example, the frame 47 is made of a conductor (conductive material), and the frame 47 and the shield members 50 and 51 are electrically connected and set to the ground potential. Therefore, in this embodiment, as an example, noise mixing with respect to an electric signal is more easily suppressed. The frame 47 is an example of a shield member. The shield members 50 and 51 are an example of a frame.

  In the present embodiment, as an example, as shown in FIGS. 13 and 16, the shield members 50 and 51 or the frame 47 are provided in portions corresponding to the wall portions 2g and 2h of the second support portion 2b. Absent. The walls 2g and 2h are made of a non-conductor (non-conductive material, for example, a synthetic resin material). When mounted on the stand 2, an antenna 26 (see FIG. 7) is positioned at a portion of the television receiver 1 corresponding to the wall portions 2 g and 2 h. Therefore, according to this embodiment, it is easy to suppress that the communication performance of the antenna 26 falls by the shield members 50 and 51 or the flame | frame 47 as an example. That is, in the present embodiment, as an example, the portion corresponding to the antenna 26 is at least one side (in the present embodiment, as viewed from the front of the display screen 4a with the television receiver 1 mounted on the stand 2 as an example. Front and side) are exposed electromagnetically (not covered with a conductor).

  In the present embodiment, as an example, as shown in FIGS. 9, 10, 12, and 17, the component housing portion 41 includes a wall portion (upper wall, top wall, first wall portion) 41 a positioned above. Wall part (side wall, vertical wall, standing wall, standing wall, second wall part) 41b located on the left and right sides in the rear view (front view) 41b, wall part located on the rear side (rear side) (rear wall, back wall) Wall, second wall portion) 41c. The wall portion 41 b is an example of a side end portion of the component housing portion 41. Further, the wall portion 41 c is an example of a rear end portion of the component housing portion 41.

  In the present embodiment, as an example, as shown in FIGS. 10, 12, and 17, the connector 44 is exposed from an opening 41 e provided on the surface 41 d of the wall 41 c of the component housing 41 (housing 40). doing. In the present embodiment, as an example, the end 2a3 of the first support portion 2a is connected to the open side of the connector 44 (open side, open side of the opening 41e) with respect to the wall 41c (surface 41d, end). In this embodiment, as an example, they are separated rearward). That is, in the present embodiment, as an example, the first support portion 2a includes a protruding portion (an overhang portion, a flange portion, an extension portion, a peripheral portion) that protrudes rearward from the wall portion 41c and from the wall portion 41c to the open side. Part, peripheral part, bottom part, floor part, leg part, wall part) 2a1 is provided. In addition, in this embodiment, although the protrusion part 2a1 is provided in flat form as an example, it can be comprised by various shapes. For example, the projecting portion 2a1 may be in the shape of a band, rod, mesh, or ring, and may be provided with an opening such as a notch or a through hole, or an uneven portion. In the present embodiment, as an example, the projecting portion 2a1 covers a connector, a cable (harness, wiring), and the like (not shown) coupled to the connector 44 from the lower side. That is, the protrusion 2a1 is an example of a cover (a cover or a protection). Further, since the protruding portion 2a1 protrudes from the wall portion 41c, it is possible to prevent other objects (walls, devices, parts, etc.) from hitting a connector, a cable, or the like coupled to the connector 44. That is, the protruding portion 2a1 is an example of a suppressing portion (protecting portion). Further, the projecting portion 2a1 extends along the placement surface P (see FIG. 9) in a direction intersecting with the rear (in this embodiment, as an example, an orthogonal direction, a left-right direction in a front view and a rear view). Is also extended. That is, the protruding portion 2a1 protrudes laterally from the wall portion 41b. Therefore, as an example, it becomes easy to secure a space (region) through which the connector and the cable are passed above the protrusion 2a1. The protrusion 2a1 can be provided with a mechanism for hooking or fixing the cable (for example, a protrusion, a wall, a recess, a groove, a hook, a hook, etc.). Moreover, the opening part 41e may be provided in the wall part 41b, and the connector 44 may be exposed from the said opening part 41e.

  In the present embodiment, as an example, as shown in FIG. 17, the wall 40 (bottom wall, bottom) 40 a of the housing 40 is recessed (projected) and away from the placement surface P (upward). A protruding portion (concave portion) 40b that protrudes toward the bottom is provided. And the board | substrate 42B is couple | bonded with this protrusion part 40b with coupling tools (not shown), such as a screw. Therefore, according to the present embodiment, as an example, a configuration in which the substrate 42B is provided at a position away from the placement surface P can be obtained as a simpler configuration. Moreover, the rigidity of the housing | casing 40 tends to become high as an example by the protrusion part 40b.

  Also, in the present embodiment, as an example, as shown in FIGS. 1 and 20, the television receiver 1 corresponds to the speaker 31 provided in the housing 3 in a state where the television receiver 1 is located at a predetermined position of the stand 2. A notch 80 (opening, recess) is provided facing the opening 3u, that is, the opening 3u (see FIG. 2) where the speaker cover 3t covering the speaker 31 is provided. In the present embodiment, as an example, as shown in FIGS. 1 and 2, speaker covers 3t, openings 3u, and notches 80 are provided at two locations on the left and right sides in front view with respect to the display screen 4a. . The speaker 31 is provided corresponding to each speaker cover 3t.

  The notch 80 is provided at a corner portion that is a boundary portion (connecting portion, crossing portion) between the wall portion 2 e and the wall portion 2 h of the stand 2. The notch 80 has an end t1 on the wall 2e side facing the opening 3u, and an end t2 on the wall 2h side located on the front (ie, front) side of the display screen 4a. Moreover, the notch part 80 is comprised as a recessed part (concave groove part) which has wall part 80a, 80b. The two wall portions 80b extend across the placement surface P (in the present embodiment, orthogonal to each other as an example) and face each other with a gap therebetween. Further, the wall portion 80a extends across the wall portion 80b across the two wall portions 80b. By these wall portions 80a and 80b, the cutout portion 80 is configured as a concave groove portion extending along the normal direction of the display screen 4a.

  In such a configuration, the notch 80 constitutes at least a part of the propagation path of the sound S coming out of the opening 3u. Here, the wall 80a approaches the mounting surface P as it goes from the end t1 to the end t2. Therefore, according to the present embodiment, the sound S emitted from the opening 3u is reflected by the wall portions 80a and 80b and the housing 3, so that the notch 80 extends, that is, along the wall portion 80a. It is easy to go in the direction. In such a configuration, the user may easily hear the sound S due to reflection on the placement surface P or the like.

  In the present embodiment, as an example, as shown in FIG. 1, the stand 2 covers both sides in the longitudinal direction of the end portion 3 e of the housing 3 with wall portions 2 g and 2 h (cover portions). In the case of such a configuration, since the area (area) where the surface (front surface 3a, rear surface 3b, side surface 3p, etc.) of the housing 3 is covered with the stand 2 becomes wide, it is difficult to secure the exposed opening 3u. In some cases, restrictions on the layout of the opening 3u and the speaker 31 may increase. In this respect, according to the present embodiment, a part of the propagation path of the sound S can be configured by providing the cutout portion 80 even in a portion where the surface of the housing 3 is covered with the stand 2. Therefore, as an example, the user can easily hear the sound S at a higher volume. In other words, the degree of freedom in layout of the speaker 31 and the like in the housing 3 is likely to increase due to the notch 80. Therefore, as an example, the support rigidity of the housing 3 by the stand 2 and the securing of the volume of the sound S from the speaker 31 are easily compatible.

  In the present embodiment described above, as an example, at least a part of the propagation path of the sound S output from the opening 3u that is positioned corresponding to the opening 3u from which the sound S from the speaker 31 is output is provided on the stand 2. The notch part 80 to comprise was provided. Therefore, according to the present embodiment, as an example, it is easier to hear the sound S from the speaker 31 than when the opening 3 u is blocked by the wall 2 e of the stand 2. As an example, the degree of freedom of layout of the speaker 31 in the housing 3 is likely to increase.

  In the present embodiment, as an example, the end t2 of the notch 80 opposite to the opening 3u of the speaker 31 is opened to the front side of the display screen 4a. Therefore, according to the present embodiment, as an example, a user located on the front side of the display screen 4a can more easily hear the sound S from the speaker 31.

  Moreover, in this embodiment, the wall part 80a which goes to the mounting surface P side as the wall part 80a of the notch part 80 goes to the edge part t2 from the edge part t1 as an example was provided. Therefore, according to the present embodiment, as an example, the sound S from the speaker 31 is likely to be directed toward the placement surface P, and as an example, the sound S is easily heard by reflection on the placement surface P.

<First Modification>
In the present modification, as an example, as shown in FIG. 21, the stand 2 has a notch 80 </ b> A similar to that in the first embodiment. Therefore, the same result as in the first embodiment can be obtained also in this modification. However, in this modified example, as shown in FIG. 21, the wall 80a is curved in a state in which the stand 2 is convex toward the placement surface P side and the opposite side to the display screen 4a. The wall part 80a is an example of a curved part. According to this modification, as an example, a place where the sound S can be easily heard is easily set by the curvature of the wall 80a. The position and shape of the curve can be changed as appropriate.
